GRAIN AND SEED CLEANER.

Applieatioii filed March 5, 1927. Serial No. 173,064.

ihe invention has relation to grain and seed cleaners, having for anobject to provide an efiicient machine for this purpose wherein theupper half of the fan casing or drum may be removed readily tofacilitate cleaning and repairs. Other objects and advantages willhereinafter appear; i

The invention consists in the novel construction and combinations ofparts as set forth in the appended claims.

In the accompanying drawings, illustrating the invention, Figure 1 is acentral vertical longitudinal section of the machine;

Figure 2 is a side View of the machine; Figare 8 is a side view of theopposite side of the machine, showing the machine folded for compactnessin shipping and storage; Figure 4 is a plan view partly broken away;Figure 5 is a detail perspective view of the strap metal bracket; Figure6 is a detail View of the lower end of the lower shoe showing the hangermeans therefor; Figure 7 is a detail perspective view of the upperremovable section of the drum; Figure 8 is a detail View of the lowerpart of the upper shoe showing the screen retaining brackets; Figure 9is a detail end view of the lower shoe.

In these drawings the numeral 1 designates the hopper for discharge ofthe grain or other material upon the upper chaif screen 2. The uppershoe 3 in which this screen is mounted has a screen board 4 thereunderbelow the discharge end of which is an inclined grain de- Hector 6delivering the grain rearwardly the latter delivering the grainforwardly to the upper screen of the lower shoe 9, said lower shoe beinginclined reversely tothe upper shoe. The fan casing or drum 5 is mountedat one end of the machine and is divided centrally by a verticalpartition 10,the transverse fan shaft 11 having the fan blades 12located in one end portion or half of said drum between said partitionand the side frame structure.

The operation of the fan creates a suction to cause the air to enterbelow the grain de-i flector 6 and between the same and the oppositelyinclined grain deflector 7, thence pass- 7 ing into the longitudinal airduct 13, the free end of the bottom of which is formed by said graindeflector 7, the top 13 having at its outer end a downturned lip 13opposite, to grain deflector 7 and forming therewith the mouth of theair duct and the upon an oppositely inclined grain deflector 7, theadjustmentof said air duct bottom wall 14 thereof having an upwardlyrenaez humped or curved portion 15 and a reversely bent rear end portion16 continued into said drum at the end or. half thereofopposite to thatin which the fan is located and being lodrum and on a level with thecentral opening 17 in said partition 10. Transverse frame memberslfsupportbottom wall 14;. The grain discharged upon the oppositelyinclined graindeflectors 6 and 7 will be re tarded in its downward pathand during this retardation will'be exposed to the suction draughtentering the mouth of the air duct, which will carry the lighterparticles and im purities over the humped portion ofthe air duct intothe said drum, whence they will be withdrawn through the centralopening] of the partition 10 into the fan chamber and thence dischargedthrough discharge passage 1 18 in a direction directly opposite tofthattaken through the air duct into the fan casing, said discharge passagebeing located below the air duct and between the bottom ofthe same andthe topof the lower shoe, the latter being covered by plate 19,the lineparticles and impurities being driven out through lateral outlet opening18 of said discharge passage at theside of the machine and well spacedapart fromthe grain discharge at the lower end of the lower shoe. An airdeflector 19 is located in the discharge passage 18 and is adjustable tovary the draught, and maybe '60 cated above the bottom wall proper ofthe said provided with a thumb nut upon itspiv'ot to fan blades willyield should they contact therewith, and at the end of the inwardmovement the said removable half lscammed upwardly by engagement of thecam edges 21 r of the central bearing perforations QQ and V will thendrop gravity said camedges abutting against the camshaft, to hold thement, a turn button 23 being employed to movement. V p I V The cleaningof the grain or otherniaterial positively hold the drum against outwardV 10a drum half against accidental outward move machine, the lower endsof said shoe being hung or suspended from hanger rods 28, the

latterat their upper ends pivotallyand slidably engaging perforations 29ofhorizontal brackets 30 and havingan ularl turned free ends 31 restingupon said brackets.

The fan is driven by large gear wheel 32, having a chain belt connection33 with pinion 34, the latter having a crank and pitman connection 35with the upper end of one of said rocker levers, the pitman beingextended beyond therocker lever and at its inner end having pivotalconnection at 36]. with the lower end of a rocker link 37 by means of atransverse rod 38 connecting the lower ends of the rocker links atopposite sides of the machine. The fan shaft at its opposite end has asimilar crank and pitman connection 35 with the opposite rocker lever,the pitman being similarly extended beyond the rocker leverand at itsinner end having connection with the lower end of the opposite rockerlink 37. The upper shoe is provided at its inner end with open ends10ts39 engaging the transverse rod 38, the outer end of said shoeresting and sliding back and forth upon the outer ends of the sideboards 40 for the air I duct and fan casing. The upper shoe may bereadily lifted from engagement with said transverserod and removed fromthema- ClllIlO. The transverse rod 38 1s ad uStable to upper and lowerpositions in perforations 41 of said rocker links in order to give theshoe a; greater or less inclination or pitch and r a. shorter'or longermovementof reciprocation.

'The chaff screen 2 of the upper shoe is held in place by the side wallsand inner wall of the shoe and at its outer end is dropped into placebehind sheet metal abutment corner brackets 42 ofthe shoe, forming a.simple means for holding the screen in place. Said "corner bracketsengage horizontal slots 42 of the shoe.

Tn thereciprocation of the shoes, the hanger rods 28 take a fulcrumhearing at the terminal ends oftheir angularly bent upper end portions31 upon the horizontal brackets 30 from which the hanger rods are hungto cause the forward or lower end of the screen'to kick'up'ateach'rearward movement of 'reciprocation and to fall at each forwardmove ment of reciprocation, thereby effecting astandards 43 at each sideconnected at the top by the hopper side boards 44, intermediately oftheir length by the side boards 4.0 of the fan casing and air duct, andat their lower: ends by theropen top base box 45. These standards 43 aredivided intermediately of their length at 46, having each upper andlower end abutting sections connected together by pivoted links L7,whereby the entire machine, with the exception of said base box and thelower standard sections may be dropped or folded downwardly and forwardly to the position shown in Figure 3, the upper standard section foldingin parallel to the lower standard sections, upon the lower pivots ofsaid links as centers, thereby reducing Inaterially the cubic contentsof the machine and lower end of the shoe to rise the full length of isaid rods and the upper end of'the shoe will slide forwardly from overthe transverse frame bar 49 connecting the side boards 40 and locatednormally below the rear end of the shoe.

Thescreen frame 8'is slid'readily into and out of place in the lowershoe owing to the fact that it slides in loose fitting seats located atthe sides of the shoe, said seats being formed by the bottom of the shoeand the upper side by molding'strips 9 on the sides of the shoe.

strip 50 which holds it upwardly against said molding strips and theupper end of the screen frame is held upw rdly against the moldingstrips by means of a strap metal 52 hearing against the screen; frameand an iii-turned lower end having slot 53' engaging a bolt 54 of thebotton'i of the shoe, said bolt havm a thumb nut 55 to ix the adListment. Upon release of said thumb nut the bracket may be slippeddownward y beneath the shoe bottom, to admit of read insertion andremoval of the screen frame due to the fact that the bolt engages theslot: 53 of the bracket admitting of endwise movement of "the bracketand to the fact that the free end of the lower flange or end of thebracket is down-turned at 57.

The hopper has a bottom slide gate 58 which is adjusted outwarc ly andinwr dly by means of ahopper rod 5?), said rod being of considerablelength and midway of its length bearing against a transverse abutmentThe lower end of the screen frame is providedwith a transverse bottombracket'ol havin an outturned u) 361' end strip 60 secured to the hoppersides. A downwardly projecting clamp bolt 61 is carried by said slidegate and engages a perforation it; theouter or free end of the hopperrod whereby when the thumb nut of said boltistight'ened the free endportion of the hopper rod will take a bearing against said strip 60 andbe sprung upwardly to draw said slide gate downwardly into strongfrictional engagement with the top of said abutn'ient strip and to drawsaid hopper rod upwardly into strong frictional engagement with thebottom of said strip, the result being that the slide gate is heldstationary against displacement in any position of adjustment.

The upper and lower screens of the lower shoe discharge at thelower endof the shoe at opposite sides thereof into suitable receptacles placedthereunder, and the smaller seed or grain passing through both screensare discharged through lower spout 63 of said shoe into the base box e5.The upper shoe dis charges the chaff at the opposite end of the machine.
